+## Line Notifications
+* **Source**: https://line.me
+* **Icon Support**: Yes
+* **Attachment Support**: No
+* **Message Format**: Text
+* **Message Limit**: 5000 Characters per message
+
+## Account Setup
+1. First download Line in order to use it via [Google Play](https://play.google.com/store/apps/details?id=jp.naver.line.android) or [Apple](https://apps.apple.com/us/app/line/id443904275).
+1. Once installed, you need to open up the software on your mobile device and access the :gear: icon and click on **Accounts**.  From here you need to associate an Email address with your account if you haven't done so already.  There is a validation process you must complete.
+
+### Generate a Token
+In order to generate a token, you need to have associated an email address with your account so that you can log into the [developer console here](https://developers.line.biz/console/).
+1. Create a **Provider** if you haven't done so already; when prompted you want to create a **Messaging API**
+1. Next you'll need to create a **Channel**.
+     - On the **Basic settings** tab you can acquire your BOT **User ID**.  This is suggested to become your `{user}` Apprise field.
+     - On the **Messaging API** tab you can **Issue** a Long Lived **Channel access token**.  This will become your `{token}` Apprise field.
+1. In your Channel settings under the **Message API** tab:
+      1. you may want to optionally turn off **Greeting messages**; I personally find it annoying but you may not.  So this is up to you.
+      2. On your mobile device, you will want to chose to add a friend and scan the QR Code under this **Message API** tab (near the top)
+
+## Syntax
+Valid syntax is as follows:
+* `line://{token}@{user}`
+* `line://{token}@{user1}/{user2}/{userN}`
+
+### Parameter Breakdown
+| Variable    | Required | Description
+| ----------- | -------- | -----------
+| token    | Yes      | This is the **Long Lived Access Token** generated from the [Line](https://line.me) console (under the Message API section of your channel).  This is a very long token that ends with an equal sign `=`.  This token also contains numerous forward slashes in it `/`.  Apprise is able to detect the API and distinguish it apart from the one or more users you've added. So you can safely paste the entire token **as is** straight into the URL.
+| user        | Yes       | The Line users (separated by forward slash `/`) that you wish to notify.  This is NOT the `@userid` you can acquire from your mobile device.  It is instead the Line User ID (which usually starts with the letter `U`). For example, you can acquire your Line BOT User ID from the [developer console](https://developers.line.biz/console/) within your channel settings under the **Basic settings** tab (at the bottom).
+| image    | No       | Associate the notification status via a represented icon.  You can set this value to `no` if you do not want this to occur.
+
